Grade Harbor helps K–12 writing teachers turn grading into better instruction. Our AI-assisted platform prepares rubric-aligned scores, evidence-based feedback, and criterion-level explanations for teacher review. Teachers can edit, override, and approve every grade and piece of feedback before it becomes final. Grade Harbor also surfaces writing-skill patterns across students and classes, helping educators identify instructional priorities, group students by need, and plan targeted next steps. AI prepares the work. Teachers make the decisions.
